ROD-MILL.

SPECIFICATION forming part of Letters Patent No. 451,673, dated May 5,1891.

Application filed December 26, 1890. Serial No. 375,840. (No model.) v

To all whom, it may concern."

Be it known that I, IRVING A. KILMEE, a citizen of the United States,residing at Newburg, in the county of Orange, State of New York, haveinvented certain new and useful Improvements in RodsMills, of which thefollow-' ing is a specification, reference being had therein to theaccompanying drawing.

This invention relates to certain new and useful improvements inrod-mills; and it has for its objects, among others, to so arrange theparts or elements comprising the plant that the necessity of providing afloor over one or more of the shafts of the rolls for the accommodationof the workmen is avoided.

It has for a further object the provision of improved means forimparting power to the several shafts.

A further object is the economy of space by bringing the dilferentshafts and trains into as close proximity to each otheras consistentwith good results. I so arrange the parts that all of the repeatersorguides will be upon one side of the shaft, so that the said shaft neednot be protected or covered. The power is imparted to the differentshafts from an engine or engines with pulleys and belts compactlyarranged.

Other objects and advantages of the invention will hereinafter appear,and the novel feaures thereof will be specifically defined by theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, forms a part ofthis specification, and in which is shown a plan of my invention.

Referring now to the details of the drawings by letter, A designates themain operating shaft, which is journaled in suitable bearings andarranged to be driven from any suit able motor, either a single ordouble engine beingshown as provided with one crank a,

although there may be another upon the other end of the said shaft. Theplant comprises four series or trains of rolls consisting of abillet-train B, a side train 0, and two finishing-trains D and E. Thefinishing-trains are arranged with one shaft extended beyond the otherand the two located relatively between the billet and side train. Therolls of theseveral trains are preferably, though not necessarily,located outside of the rolls of the adjacent trains, so as to avoidtangling of the rod by'reason of slack or surplus and to provide for theoverfeeding of the rod without danger of stopping of the mill or injuryto the rolls or rod. The finishing-trains are arranged within the limitof the billet. and side trains, but beyond the ends of the shaftsthereof, so that all of tlie curved guides or repeaters F shall be uponone side of the mill, thus avoiding the necessity of a flooring or otherprotector for the shafts, which would be necessary if the trains were soarranged that the repeaters were upon the other side of the shaft. Thesecurved guides or repeaters may be of any of the well-known forms ofconstruction and avoid the necessity of catchers at these points.

It may sometimes be found desirable to so arrange the trains that theworkmen may be arranged with catchers where the rod emerges from therolls in a rectangular cross-section and where the flooring over theshaft is not objectionable, in which case I arrange the finalfinishing-train as indicated in dotted lines in the drawings; but theformer arrangement is much preferred.

On the main shaft I arrange the four pulleys G, H, I, and J, the threeformer of sub-' stantially the same size, while the latter is muchsmaller. On the shafts of the several trains I arrange the pulleys M,N,O, andP, that on the shaft of the billet-train being the larger and thaton the side train smaller, and those on the shafts of the two sectionsof the finishing-train being still smaller than that of the side train,at. (1 preferably of varying size, as shown, so that the differenttrains will be run with different velocities, the shaft of thebillet-train revolving the slowest and that of the finishing-train thefastest, so as to prevent slack between the trains.

Suitable belts K are provided for communicating power from the mainshaft to the various train-shafts, as indicated by dotted lines.

The initial roll of the side train being arranged outside the final rollof the billet-trainpermits me to use a straight guide L from thebillet-train, and a catcher is employed at this point to guide the rodto the initial roll of the sidetrain.

\Vhat I claim as new is- 1. A plant for rolling billets to rods,comprising a hillettrain, a side train, and a finishing-train insections, arranged between the side and billet trains,with the rolls ofboth sections beyond the final roll of the side train, as set forth.

2. A plant for rolling billets to rods, comprising a billet-train, asidetrain in proximity thereto, with its initial roll beyond the final rollof the billettrain, and an intermediate finishing-train in sections,with the rolls of each section beyond those of the adjaeentsection andthe initial roll of the first section be yond the final roll of the sidetrain, as set forth.

A plant for rolling billets to rods, comprising; a billet-train, a sidetrain, and a fin ishing-train with the repeaters all upon one side ofthe train, as set forth.

4. In a rod-mill plant, a side train, abillettrain, and an intermediatefinishing-train in sections, with the rolls of the several trains beyondthe limit of those of their next adjacent train, pulleys on the severalshafts, and con neotions with the main actuating-shaft, wherebydifferent speeds are given the shafts of the several trains, as setforth.

5. In a rod-mill plant, a billet-train, a side train in close proximitythereto, and an intermediate finishing-train in sections, the shafts ofthe sections extended one past the other and the rolls of the severaltrains arranged with their initial and final rolls beyond the limits ofthose upon either side thereof, substantially as specified.

(5. In a rod-mill plant, the series of rolls arranged with repeaters,all extending in one direction from the initial roll of the billettrainto the final roll of the finishing-train, whereby a protector over theshaft extending from the final roll of the billettrain to the initialroll of the finishing-train is obviated. as set forth.

In testimony whereof I atfix my signatu re in presence of two witnesses.

IRVING A. KILMER.
